Hailer operation
The IC-M603 has a 2-way hailer function for voice amplification
and reception over a loudspeaker, making it unnecessary to
leave the bridge to hear a hailing party. During hailer operation,
transmitting is impossible and the received signal is muted.
Connect an external hailer speaker as described on p. 46.
